Description

Tapered roller bearing

Technical Field

The utility model relates to a bearing technical field specifically is a tapered roller bearing.

Background

The tapered roller bearing belongs to a separation type bearing, an inner ring and an outer ring of the bearing are respectively provided with a tapered raceway, the bearing is divided into different structural types such as a single-row tapered roller bearing, a double-row tapered roller bearing and a four-row tapered roller bearing according to the number of rows of rollers, the single-row tapered roller bearing can bear radial load and single-direction axial load, when the bearing bears the radial load, an axial component force is generated, so that another bearing capable of bearing opposite-direction axial force is required to be balanced, in the using process of the bearing, lubricating oil is added into the bearing according to the using requirement, most of the prior art is directly poured into a gap between the inner ring and the outer ring, the using amount of the lubricating oil is increased, and the lubricating oil cannot be uniformly distributed between the inner ring and the outer ring, so that the using requirement of people cannot be met.

SUMMERY OF THE UTILITY MODEL

In view of the problems in the prior art, the utility model discloses a tapered roller bearing, which adopts the technical proposal that the tapered roller bearing comprises an inner ring, an outer ring and a retainer, the retainer is arranged between the inner ring and the outer ring, the retainer is provided with rollers which are uniformly distributed on the retainer, and a separation plate is arranged between the rollers, a clamping groove is arranged at the position of the inner ring corresponding to the rollers, a rolling structure is arranged on the surface of the clamping groove, an oil storage groove is arranged in the inner ring above the clamping groove, the top end of the clamping groove is communicated with the oil storage groove through an oil outlet, the joint of the oil outlet and the oil storage groove is arranged above the bottom end of the oil storage groove, an oil filling channel is arranged at the position of the surface of the inner ring corresponding to the oil storage groove, the oiling channel is connected with a sealing column in a rotating mode, and an oil receiving groove is formed in the position of the bottom end of the clamping groove.

The rolling structure comprises a mounting hole arranged inside the clamping groove, and a rolling ball is connected in the mounting hole in a rolling mode.

The top of the sealing post is provided with a clamping post, and the top of the oil injection channel is provided with a counter bore at a position corresponding to the clamping post.

The utility model has the advantages that: the utility model discloses an oiling passageway adds lubricating oil to the inside of oil storage tank, can follow the inside that the oil-out entered into the draw-in groove after lubricating oil fills up the oil storage tank, rotate the outer lane this moment to make lubricating oil can be attached to on the roller, and the lubricating oil that flows down along the draw-in groove finally can be collected in connecing the oil groove, thereby can prevent that lubricating oil from flowing out, the use of lubricating oil has not only been practiced thrift, and make the branch that lubricating oil can be even between inner circle and outer lane, thereby people's user demand has been satisfied.
